# Factor Group and Torsion Group

Heres my problem.

Consider the group <R,+> (reals under addition) and its normal subgroups Z (integers) and Q (rationals0. (These are normal because R is abelian,

of course.)

(i) Find an element of Q/Z of order 350.

(ii) Show that Q/Z is the torsion subgroup of R/Z. This problem is quite straightforward if you use the definitions and stay focussed; in

particular, pay attention to the definition of a rational number.

(iii) Show that R/Q is torsion free. Think carefully about the elements of R that are not in Q here.
